I purchased 25 feet of 0 AWG form a supplier on eBay for $45 ($12 shipping) and four brass (supposedly gold plated) battery connectors ($7.49).
I constructed four five foot cables in just over one hour. Battery connectors were converted to spades with a cold chisel and wire cutters, cable was cut with a hacksaw and insulation stripped with the hacksaw. Spades were connected to Pass Labs 250.5 terminals (PL does not supply banana plug receptacles). I attached banana plugs to a two inch piece of silver plated 8 AWG wire. I hollowed out a holle in 0 AWG wire with a punch and did not remove insulation. I then inserted the stripped 8 AWG wire in hole and secured the assembly with a hose clamp around the insulation at the cable’s end.
The cables were attached to my thirty year old modified MG IIIa’s. The results are stunning. The amount of undistorted energy filling the room, is jaw dropping. I keep turning up the volume to levels that previously irritated my ears, and experience no irritation. In the modified lyrics of B.B. King, “The shrill is gone.” My wife is hearing new detail in cuts she has listened to many times before.
In my case, b4icu, you were absolutely correct, thank you (except for the part of you doubting ribbon speakers would be improved with installation of your design). I can’t wait to try the cables in one of my other systems that employs cone speakers.
I am am sure every case is different. Nevertheless, I encourage other hobbiest to test your theories.
Thank you for your generosity and patience.
All good wishes
